Spektrum-Aufspreiz-Kommunikationssystem |
摘要 |
A spectrum spread communication system capable of preventing an increase in error rate irrespective of hit while keeping a communication speed from being reduced. A plurality of input data DS-modulated by a DS spread multiplier are fed to an array converter, wherein a first chip of each of the data is collected to form an FH first frame. Likewise, only second to seventh chips are collected to form FH second to seventh frames, respectively. The FH frames each are then subject to FH modulation in an FH spread multiplier and then transmitted. In a receive section, the data are returned to the original data array after FH demodulation, resulting in a burst error being a random error. |
